Titanium dioxide (TiO2) is one of the most promising materials for photovoltaics and photocatalysis nowadays. This material appears in different crystalline forms, but the most attractive one for applications is “anatase”. EPFL scientists have now shed light onto the problem by a combination of steady-state and ultrafast spectroscopic techniques, as well as theoretical calculations...

Jenway offers a range of visible and UV/visible spectrophotometers including single beam and diode array entry level spectrophotometers, split-beam spectrophotometers with a spectral bandwidth of 1.5nm; and advanced variable double beam spectrophotometers with a variable spectral bandwidth down to 0.5nm

To ensure that the removal and treatment of our sewerage meets increasingly high standards, it is important to be able to monitor the water online both to provide timely information and also to establish changing patterns over days, weeks and seasons. In their article “On-line monitoring for improved wastewater system management: applications of ultraviolet/visible spectroscopy”, Rita Brito,...

The new and improved S11850-1106 and S11851-1106 back-thinned CCD linear image sensors from Hamamatsu Photonics have improved etaloning characteristics and high sensitivity designed for spectrometry applications.

Scientists at Chalmers University of Technology, Sweden, have developed a new way to study nanoparticles one at a time using plasmonic nanospectroscopy, and have discovered that individual particles that may seem identical in fact can have very different properties. The results, which may prove to be important when developing new materials or applications such as hydrogen sensors for fuel cell...
